Er... I believe Alan Guth has stated that the speed of Inflation could be
hundreds of times the current speed of light. That is just our universe
universe, and obviously suggests a variable C. Susan Randall and Raman
Sundrum have advocated a physically, enormous 5th dimension. They why and the
how of it, I don't have the capacity to explain or properly comprehend.
However, the following seems to be a somewhat, useful explanation by one of
the authors in the following article. Hope it helps.

Paul asked:
<<I think a more intersting question that is not
answered in Max Tegmark's amazing Sci Am piece, is how
an infinitely large Level 1 multiverse came into
existence in a FINITE period of time. He talks about
the big bang occuring just 14 billion years ago, while
saying that the present multiverse is infinite in
size. Am I missing something, or is he saying that
the SPEED of inflation is infinite therefor you can
get an infintely sized universe in an arbitrarily
finite period of time?? What am I missing??
